I have a question maybe one of you guys can help me with, I have a old but new M&R 100cc twin with a CH Ignition on it, Now the spark plug wires from the ignition are all rubber with a piece of ground strap that is screwed to the cyl. head, Now my question is on the back of the ign. box it says 4-00 ss OK and then initials LM. and then says sinco spark or something like that. Now this is in a 1/2 scale Pober Pixie that I am getting ready to fly and wanted to know if it would be better to run a big 4.8 v pack or can i run a A-123 pack, ?? I am worried about to much voltage in the ign.
and also the rubber boots on the plugs verses the metal ones.

any input would greatly be appreciated.
